Abstract: The optimum macroporous resins for purification of flavonoids in Lycium barbarum L. were screened by static adsorption method. The purification process of flavonoids in L.barbarum L.was optimized through dynamic adsorption experiment. The static adsorption results showed that macroporous resin HPD100 had a highest adsorption in the four types of macroporous resins, and its adsorption rate reached 82.15 %. The dynamic adsorption results showed that when the injecting velocity, injecting concentration, elution solution concentration and eluting velocity were 2.0 mL/min, 5.0 mg/mL, 50 % ethanol and 1.5 mL/min, respectively. The purity of the total flavonoids achieved 78.53 % and the recovery reached 71.35 %.
